Anthropic's cybersecurity-focused AI model, Mythos 5, remains limited to selected US organizations through Project Glasswing after the Trump administration dropped export controls on the company's latest AI models. Global users can access Fable 5 starting Wednesday, but talks continue over broader domestic and international access, with the US government reportedly directing which institutions regain access. Anthropic first previewed Mythos in April, initially giving 50 vetted institutions access before expanding Project Glasswing to 150 organizations across 15 countries in June. That rollout was disrupted when the Commerce Department imposed export controls on June 12, requiring Anthropic to obtain US permission before allowing any foreign national to access Fable or Mythos. The restrictions were introduced after Amazon security researchers reportedly found a workaround for Fable 5's safeguards, allowing the model to uncover cybersecurity vulnerabilities. The US later eased some restrictions on Mythos and dropped the export controls on Tuesday after Anthropic added new classifiers to Fable 5. Anthropic is now restoring access to its original US Glasswing partners, but the company said there is no timeline for when international partners may be included.
